Does anyone know if the regulator that goes with the holley blue 14PSI fuel pumps need a return line? How do they regulate the pressure?

From what I remember it is only a dual port regulator, one in and one out. It internally regulates without a bypass port. On the project I'm working on we are ordering the Holley 12-803BP regulator. It is a 3 port with return and are going to regulate the pressure after the carb.

i run a holley blue on my truck. but the old guy told me to throw away that regulator that came with it. i have a BG regulator, after the carb as well. this guy has raced for years so i guess he knows what he's talking about

What do you mean a regulator after the carb?

+1... This is what I had on my old K10 and worked flawlessly.
The part is a BG "bypass" regulator.
This is what I used (and probably crazyhole812, too) - http://www.barrygrant.com/bgfuel/default.aspx?page=49 , look for the "bypass diaphram" at the bottom of the page.
